Script to open another form

I have a form that displays a chart, I added a button that when clicked it's supposed to open another form "C_myForm" (created it as a Data Form in the architect) that is made up of a datagrid, but it's not working. When I click the button nothing happens.

Below is the script I used: Application.BasicFunctions.DoInvoke "Form", "Personal: C_myForm"
